A sink auger (also called a drum auger or canister auger) is the ultimate weapon for breaking up and clearing clogs in sink and tub drains. Just don’t use it on toilets—they call for a closet auger or toilet auger (see next slide).
A sink auger consists of a flexible stainless steel cable with a corkscrew tip at the end. The cable is coiled within a drum canister and is extended into a drain to reach a clog and clear it. The drum has a handle, and there’s a thumbscrew that locks the cable to the canister, and when you insert the cable into the drain and turn the handle, the rotating drum snakes the cable through bends in the drain pipe, allowing the cable tip to penetrate clogs and pull them out.
